Moore shares his time between his home state and New York City, where he owns a Manhattan apartment.

The couple did not disclose how their fortune would be divided, with Moore commenting on his Facebook page: “Kathleen and Michael have mutually and amicably reached a divorce settlement.”

In an ironic postscript, Moore added a clip of Bruce Springsteen's Rosalita (Come Out Tonight) to the update. The divorce proceedings had been ongoing since June last year.

‘Serious financial losses’

Moore admitted in the legal proceedings that Ms Glynn’s spending had led to “serious financial losses” during their two decade-long marriage. In court documents, Moore said that in 2011 the pair had agreed that he take responsibility for signing the couple’s cheques.

Ms Glynn was involved as a producer in Moore’s films, and in 1998 the couple co-wrote Adventures in a TV Nation, one of nine books penned by Moore. The book charted the pair’s television appearances in Moore’s satirical series TV Nation, which aired in 1994 and 1995.

The filmmaker and author of Stupid White Men (2004) also said his wife had expanded their lakeside home. During the proceedings, Moore cited media reports from 2011 that had publicised renovations to the substantial property owned by the director, who had in his films described capitalism as an “evil” that should be “eliminated”.

£1.7m ‘Roger and Me’ payout

Moore made his break with Roger & Me (1989), a film charting the impact of car factory closures in Michigan. In 2011 he was paid £1.7m by Warner Brothers for world rights to the film, which was his first of nine productions. It has made £4.4m at the box office worldwide.

Moore’s best-selling film so far has been Fahrenheit 9/11, which made approximately £131m at the box office worldwide and won the Cannes Film Festival’s Palme d’Or in 2011, the festival’s highest accolade.

Capitalism: A Love Story raked in £10m in global box offices since its 2009 release.

After receiving criticism for marching during New York Occupy Movement in 2011, after having received his Roger & Me payout, Moore explained that he had spent the money on paying off debts, rebuilding a church, giving gifts to family and friends and donating one thousand turkeys to families during Thanksgiving.
